Epidemiologists use various methods to study ingestion-related health issues:
Surveillance Systems: Monitoring and collecting data on foodborne and waterborne diseases. Outbreak Investigations: Identifying sources and causes of disease outbreaks linked to ingestion. Case-Control Studies: Comparing those affected by a disease with those who are not to identify exposure factors. Cohort Studies: Following a group of people over time to assess the impact of ingestion on health.
